Resuming an Interrupted Download
If your download is interrupted due to errors or any other reason, you can resume the download using the command-line interface.
- At the command line, use the same command from the same directory that you originally used to start the CLI. Note that if the -d option is used to define the download directory, you must provide the same directory after " d."
The NBIA Data Retriever reviews what has already been downloaded, then asks “Do you want to download all or download only missing series?" - Enter A to download all, M to download missing series, or E to exit the program.
